You can batch these waffles ahead of time and store leftover waffles in the refrigerator for up to 3 days. They can also be transferred to the freezer for easy breakfasts (perfect for chaotic mornings). If reheating, we recommend using a toaster oven or a regular oven on broil (low), cooking for 1-2 minutes, flipping, and cooking for another 1-2 minutes to return them to their original crispiness.
